## Comparison

Below are some standard C libraries shipped as part of Debian Testing as of
October 2019. The numbers aren't directly comparable, as these libraries have a
richer API, especially in providing an encoder and not just a decoder. Still,
it is a reference point for e.g. Wuffs (adler32 + crc32 + deflate + gzip +
zlib) vs libz and Wuffs (gif + lzw) vs libgif.
